DELETING Environment Variables when INCORRECTLY SET

I made the mistake of resetting my ENV variables for HOME and HOMEDIR – which resulted in

a) My DOS prompt not being able to launch

b) My environment variables (Advanced Settings) not being able to launch.

The workaround is to launch the following EXE 


This should launch the ENVIRONMENT Variables configuration screen. Now, you can delete the incorrect variables – and you should be back in business.
